How to upgrade graphics output
I have a church customer running a 2013 27” 3.2 GHz i5 with 16 GB of RAM and a GeForce GT 755m 1GB GPU. They need to upgrade the video output.
I see where the CPU is upgradable but cannot tell if the GPU is upgradable to the 2GB.
OWC showed no upgrades.
Is it or is there an external upgrade possible?
